Show qemu command line from virsh

Question

I am debugging a problem with a libvirt VM starting, and I want to see the exact command line that it is going to use to start qemu. Is this possible using virsh or some other utility?

Answer 1

You can consult the libvirt logs in:

/var/log/libvirt/qemu/$vmname.log

Answer 2

It is also possible using virsh with the domxml-to-native subcommand:

virsh domxml-to-native qemu-argv --domain mydomain

Answer 3

Just saw this question. In the hope it helps others, the easiest way to see the qemu command that was used, while the VM is running, is:

ps -ef | grep qemu-system-x86
